Abstract

Several dipole partial groups are supplied with currents of different phases for deflecting the main beam direction. For at least two partial group (10,11) at least one HF transmitter (13, 14) is provided. The HF transmitters are simultaneously operable at different carrier phase position. Pref. all HF transmitters are controlled by a common reference oscilaltor (16). In front of at least one HF transmitter (14) is coupled a phase rotator (17). Phase comparators (21) may be provided for measuring the feed currents of the dipole groups. The different carrier phase position is maintained by a phase regulator.
